<p>A straight line motion producing apparatus useable in the papermaking process includes a base (6), a first arm (7) rotatable about a first axis (A-A) being stationary relative to the base (6) during rotation of the first arm (7). A second arm (9) is rotatable about a second axis (B-B) extending through the first arm (7) such that the distance betweeen the first axis (A-A) and the second axis (B-B) remains constant. The second arm (9) should be of a length relative to the distance between the first (A-A) and second (B-B) axis to produce a straight line motion at a particular location of the second arm (9) upon a constant distance per degree of rotation of the first arm (7) about the first axis (A-A). The apparatus further includes a means for rotating (11) the second arm (9) about the second axis (B-B) a constant distance per degree of rotation of the first arm (7) about the first axis (A-A) to produce a straight line motion at a particular location on the second arm (9).</p> |
